Case Study: On-Wafer Defect Reduction in Lithography

Case Study: On-Wafer Defect Reduction in Lithography

Overview The rapid increase of semiconductors in cars enables significant safety, connectivity, mobility, and sustainability improvements. As transportation transforms from being driver controlled to software controlled, automakers must look closer at their ability to measure and maintain product reliability throughout the vehicle’s lifetime.

High Purity PFA Tubing Overcomes PVC Pitfalls in Dual Containment Systems

A high purity sub-fab serves as the central nervous system of a semiconductor cleanroom. It houses chemical delivery, purification, recycling, and destruction systems. The sub-fab is where potentially hazardous aqueous chemistries and gases are stored and handled until they are delivered to the cleanroom process equipment located either in the floor above it or the building adjacent to it.

Precision Engineered Techniques for Coating Plasma Chamber Components

Migration from 2D to 3D structures for high-density memory devices changes the nature of etching and deposition processes, especially as the number of layers for 3D NAND integration grows to 96 and beyond, and new process chemistries become commonplace. The greater number of lengthy processing steps and high aspect ratio (HAR) features involved place new demands on all steps of the chip manufacturing process, including etching, deposition, and cleaning equipment. Consistent process stability becomes harder to achieve.

Defending Against Dangerous Electrostatic Discharge (ESD)

Much as a bolt of lightning can strike in one spot and travel, creating a path of destruction in its wake, a single electrostatic discharge can have a similar effect on a semiconductor manufacturer’s bottom line. For advanced-node manufacturers, the risk posed by electrostatic discharge has become amplified by the move to fluoropolymers, a consequence of stainless-steel process tool components failing to meet increased purity requirements.

The Fight for Purity in Semiconductor Fabs Begins at the Chemical Manufacturer

To meet increasing sensitivity to contaminants in integrated circuit (IC) manufacturing, semiconductor fabs have begun looking to their chemical suppliers to adopt new contamination control standards that improve quality and assist in reducing wafer defects. Each material has several touch points along the chemical manufacturing, storage, transport, and delivery journey that could add or generate contaminants. Semiconductor fabs seek assurance from their materials suppliers that they will minimize opportunities for contaminants to end up on a wafer (Figure 1).
